### 网络验证过程的测试步骤

* 1. zCore操作系统目前测试运行在Qemu虚拟机中。
假设测试机运行环境在Ubuntu 20.04, 请在本机先安装好命令`qemu-system-x86_64`, `brctl`

* 2. 硬件连接
如果有开发板，可以把开发板的有线网接口，直接用网线连接到本测试机.
此时便可以直接在开发板中的有线网卡上抓网络帧了, 如开发板中运行:`sudo tcpdump  -XXvven --number -i eth1`
(抓网络帧可以不用设置IP地址)
<br>
另：
<br>Qemu dump网络包参数：`-object filter-dump,id=net0,netdev=net0,file=packets.pcap`
<br>tcpdump查看dump包：`tcpdump -XXnr qemu.pcap`

* 3. 运行
- 3.1
```
./run.sh
```
- 3.2 此时会启动虚拟机，启动时会自动设置好虚拟网桥virbr0的网络环境, 其中本测试机是有线网是eth0, 远程开发板是eth1
```
Qemu---tap0---virbr0-----[RJ45网口]-----[开发板网口eth1]
               |
       eth0----+
```
在运行着虚拟机Qemu时，命令`brctl showstp virbr0`查看应有三个网络接口信息显示, 类似： virbr0, tap0, eth0

- 3.3 等待一会, 看到发送网络帧的如下Log.
```
[17.453635185s  WARN 0 0:0] eframe : Frame { buffer: [FF, FF, FF, FF, FF, FF, 54, 51, 9F, 71, C0, 99, 88, 8E, 1, 1, 0, 0, 0] }

```

- 3.3 此时在网络连接的开发板中,应该也能抓到一个EAPOL Start, 三个EAP Response 的网络帧:
